More analytical bite in estimating targets for shark harvest

More analytical bite in estimating targets for shark harvest

Published on 15. August 2013 More analytical bite in estimating targets for shark harvest Bradshaw CJA, Field IC, McMahon CR, Johnson GJ, Meekan MG, Buckworth RC ABSTRACT: The typically slow life histories of sharks make them susceptible to overexploitation. However, this characteristic also means that shark populations are more amenable to mark-recapture estimation of vital
